    Hi,

    I'm currently fitting a complete new floor pan to my mk1 escort,
    Before the new floor goes in I have cleaned up the inside of the chassis rails and obviously I need to to treat the bare metal,

    What would people recommended for bare metal inside the rails before the floor goes over the top?

    I'm happy to brush paint inside the rails as it obviously can't be seen when the floors in,
    I don't have any special breathing equipment for painting but obviously I want to try and protect the rails the best I can.

    Tia

    Seems epoxy primer is the way forward, is it OK to be brush painted?
    Also what mask ect would I need to brush paint it?

    Total novice when it comes to paint

    Thanks

    I use jotun 87 wintergrade as you mix it with the hardener in a 1:4 ratio, and it can be applied by brush. I dont use any mask when using it and it has a pot life of 1.5 to 2 hours when mixed. it does cost a £50ish for just under 5 litres but it is fairly thick to paint. I use it on the underneath of my cars without any other paint or coating on top of it. there are different versions though

    if you want a thinner paint you can also get lecher 29107 epoxy primer which works out £30ish for 3 litres.

    other epoxies are available but you might end up paying more and not get better results

    Unless the surface is keyed as per the epoxy manufacturers instructions (blasted or otherwise roughened up), I'd be using conventional paints - I've had epoxy on bare, smooth, metal lift off, whereas conventional paint alongside it has been fine. A good zinc primer (not convinced fully about the benefits - I'll tell you in a decade having painted inside my integrale with the stuff) or decent red oxide primer with a top coat (I used Shipley paints simply because the were along the road) - which lasted well in the decade it was used everyday. I'd be spraying some inside after welding too - recoat the welded bits. Then cavity wax.

    On correctly keyed steel - epoxy every time.
